Evanioidea Evaniidae


The representatives of the superfamily Evanioidea are easily distinguishable from all other extant and extinct Hymenoptera because of their metasoma (sometimes rounded) articulated high on the propodeum and well above the metacoxae (e.g., Goulet & Huber, 1993). Recent phylogenetic studies on the superfamily Evanioidea have shown strong support for its monophyly and for the monophyly of the Evaniidae even when fossil taxa are included (e.g., Li et al., 2018; Parslow et al., 2020; Jouault et al., 2022). According to the most recent analysis, the superfamily arose during either the Upper Triassic or the Lower Jurassic. Still, its earliest species are recorded in the younger Middle Jurassic, and its crown-group representatives during the Lower Cretaceous (Jouault et al., 2022: fig. 8). The stem Evaniidae are estimated to arise during the Upper Jurassic while their crown group has a more recent origin, likely around the Cretaceous-Paleogene boundary. Extant evaniid wasps are common, nearly cosmopolitan, and moderately diversified (about 580 extant species in 21 genera) even if this diversity is underestimated (Deans, 2005; Mullins et al., 2012). Little is known about the biology of extant evaniids, but their larvae are considered predators of cockroach eggs in oothecae (Huben, 1995). The Evaniidae have a good fossil record with the oldest species known from the late Hauterivian, numerous species documented up to the Miocene, and an important diversity in Burmese amber (e.g., Rasnitsyn et al., 1998; Nel et al., 2002; Deans et al., 2004; Jennings et al., 2012; Shih et al., 2020). Nevertheless, their past diversity is still underestimated.
